Can I update my CPU?

My mother board has a LGA 775 Socket; I have an Intel Pentium 4 Processor @ 3 GHz, and I am not sure on what will work on my pc, and what is better. I have my eye on an Intel Core 2 Quad Processor 2.66 GHz 1333MHz 4 MB LGA775. Although I know it will fit, I don't know whether it will work better than my Pentium 4 @ 3 GHz, since it only runs @ 2.66 GHz. I'm sure I can probably overclock it, but I'm wondering whether it will even be necessary; will the Intel Core 2 Quad Processor work better than my Intel Pentium 4 as it is, will I have to overclock or will it even be compatible with my computer?

Sorry, for that processor you would need a board like this one:http://www.newegg.com/Product/Produ...IF it will fit in your case AND you will need a more powerful power supply PLUS you will probably need more and faster memory to get the most out of that processor..... not worth it. Keep it as is, upgrade your graphics if you want to do some gaming, or start from scratch. Wait a little, go with a 2nd generation i5 or i7 (the i5-2500K & i7 2600K have unlocked multipliers for easy overclocking) and you will get higher quality components when you build for just a little more than a factory build. Do your research, do it right.

Truly, you would need CPU (Core 2 Duo), Motherboard ('modern' socket 775 like Gigabyte, Asus, etc), RAM (800DDR2), Power supply (wattage, available 12V Amps, proper connectors, etc), Graphics card (PCIe16-2x interface) to start with, plus a case that will fit it and probably a SATA HD and Windows 7. You will be truly building a new computer, so do it smarter and skip that generation and go to the newer i3 or i5 (or even the 2nd generation i5 which is now out). By starting entirely with a clean sheet of paper, you can choose more wisely and therefore spend more wisely and get a system you can be proud of for years. (Right now I am happy with my custom Core 2 system, but I recently built an i3-550 system for an office with mostly components a step or two over basic, and it is FAST, I am imagining what I could do with a 2nd gen. i5-2500K or even an i7-2600K. Unless I hit the Lottery, I will wait a few years.... 6 or 8 cores....SATA 6GB/s....Windows 8....hmmmm)
